Robert Chelimsky
Robert Chelimsky
Founder

Robert Chelimsky has spent nearly 35 years leading nonprofit arts organizations through growth, crisis, and transition — at scales ranging from a startup he co-founded to institutions with staffs of 75. Much of that work has been transformation under pressure — restructurings, turnarounds, and the hard organizational reckonings that follow sustained crisis.

Much of that work has been transformation under pressure. As the first Managing Director of Epic Theatre Ensemble in New York, he led a restructuring that produced a six-figure surplus and eliminated a third of the company's historical debt in a single year. At Virginia Stage Company, he renegotiated the company's lease with the City for 44% savings. At Chautauqua Theater Company, he steered the organization through steep cuts from its parent institution during the Great Recession, managed a leadership transition, led its first independent strategic planning process, and designed the search for his own successor. At the Playwrights' Center, he led the organization through the pandemic while simultaneously preparing and advancing a $19 million capital campaign — a campaign that produced a new 19,000-square-foot facility, opened in 2025. Throughout, he has treated performance as a focal point for civic dialogue — producing public conversations that invite communities to take up the questions a play raises rather than leave them at the theater door. That conviction has also shaped his approach to public funding, where he has secured millions in federal, state, and municipal investment and served as a national panelist on the congressional earmark process. A thread running throughout is identifying and mentoring the people coming up behind him. Those he has mentored have gone on to lead arts organizations, run foundations supporting artists, build careers at the senior level of international funders, and launch their own businesses. In June 2026 he founded Sillage Leadership to do that work deliberately rather than incidentally. Alongside that mentorship work, he is leading the development of Sillage Leadership France.
Bethany Gladhill
Bethany Gladhill
Managing Partner, Sillage Leadership US

Bethany Gladhill is an arts and nonprofit management consultant with a remarkably wide range — a self-described "swiss army knife" of nonprofit management.

She also holds a terminal Master of Arts in Historic Preservation — and you would be surprised how well the preservation and nonprofit fields combine. After almost two decades working with theaters in the Twin Cities (Theatre de la Jeune Lune, the Jungle, and Nautilus Music-Theater among others), she began consulting twenty years ago and has not looked back since. Her clients range from theaters to labor unions, human service organizations to think tanks, film to preschools. She's been described as a "swiss army knife" of nonprofit management, with skills ranging from financials to strategic planning, with some evaluation, fundraising, HR, and operations thrown in. She also frequently sits on grant panels, volunteers in the community, and throws spontaneous gatherings in her renovated Victorian home so that she can ask curious questions of others. Bethany has often served as an "embedded consultant" who works within organizations to affect change, but she is especially excited to see where combining viewpoints and ideas can create lasting impact. If Bethany can get you to start thinking about management in a practical way that supports your organization's core functions and makes you feel empowered in your work, she will have succeeded.
Lee Marc Molnar
Lee Marc Molnar
Managing Partner, Sillage Leadership France

For more than 30 years, Lee Marc Molnar has built his career around the belief that leadership is measured not only by what an organization accomplishes but by the people who become stronger because they were part of that experience.

Much of that work has been about building the people and systems that allow organizations to perform at their best. As Director of Production, he managed multi-million-dollar production budgets, consistently keeping operations at or below budget. But numbers only tell part of the story. Through effective leadership, he streamlined communication across departments, oversaw significant capital and facility improvements, and created and negotiated multiple union and non-union contracts. During the COVID-19 pandemic, he helped develop new operating protocols and outdoor performance procedures that allowed the organization to continue its work under unprecedented conditions. A thread running throughout his career is mentorship. Lee Marc has always believed that leadership is more than directing work and individuals — it is helping people understand why the work matters, giving them the tools to succeed, and creating opportunities to take on greater responsibility. His human resources experience, assisting national and international clients in navigating the full lifecycle of their teams, has reinforced the importance of meeting people where they are while helping them move toward where they want to go. That is the work he and his partners are now bringing to corporate organizations: turning decades of practical leadership experience into intentional mentorship that helps people — and the organizations they lead — grow.

Natalie Simonis
Natalie Simonis

Natalie Simonis has spent more than two decades leading high-performance businesses through growth, transformation, and periods of significant pressure — across luxury retail, multi-unit operations, healthcare, and high-touch service environments.

Her career has centered on building strong teams, developing leaders, and creating the conditions for people and businesses to perform at their highest level. Much of that work has involved taking businesses with significant potential and turning that potential into sustained performance. She has led organizations through rapid growth, operational change, and evolving market conditions, consistently ranking among the top 5% of performers within the organizations she has led. Her experience includes multi-unit leadership across three states as well as high-volume healthcare operations, where commercial performance, operational discipline, regulatory requirements, and client experience must work together. Natalie is particularly drawn to the human side of performance. She has built teams, recognized emerging talent, and developed people into leaders throughout her career. She believes that performance improves when people understand what is expected of them, why it matters, and how their individual contribution connects to the larger organization. Her leadership style is direct and accountable while remaining highly adaptive to the people and circumstances in front of her. Working across both luxury retail and healthcare has given her a deep appreciation for the relationship between culture and customer experience. In both environments, she has seen how leadership behaviors become organizational habits — and how those habits ultimately show up in the experience delivered to customers, patients, and employees. Today, Natalie brings that practical leadership experience to executive leaders and organizations navigating growth, performance challenges, leadership development, and change. Through her consulting practice, she works alongside leaders to strengthen teams, clarify expectations, develop leadership capacity, and turn organizational potential into lasting performance.
